SNOW-REMOVER.

Application filed October 29, 1917.

To all whom it may concern:

Be it known that I, HARRY B. Ivnns, a subject of the King of Great Britain, residing at Quincy, in the county of Norfolk and State of Massachusetts, have invented an Improvement in Snow-Removers, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be described relates to snow removers, and is an improvement upon the one shown in Letters Patent, No. 1,100,197, granted to Harry E. Plummer, June 16, 1914:.

The snow remover shown in said patent comprises a box carried on a frame pivotally mounted on a sled, and having a bottom slidable to positions for supporting or discharging the contents of the box. A scraper is mounted in the plane of the bottom in fixed position. The box and its frame may be rocked downward into position to scrape snow into the box, or lifted into position appropriate for conveying the snow to the place where it is to be dumped. By the construction described, whenever a stone or other obstacle was met in the road, it was necessary to elevate the entire box and its frame to enable the scraper to escape the obstacle and avoid jolt and injury to the snow remover. This was a difiicult, inconvenient operation adding objectionably to the duty of the driver; One of the objects of the present invention is to provide a scraper which may be readily manipulated independently of the box with adesirable nicety of control to adjust the scraper to active and inactive positions and enable it to be readily moved to escape obstacles.

Another object is to provide a controller whereby the scraper may be manipulated within a predetermined range of movement and may serve to lift the box by a further movement into its position for conveying the load thereof to the place of its discharge.

And still another object of the invention is to provide a scraper which may be moved to a position to contribute to the support of the contents of the box while it is being conveyed to the place where it is to be dumped.

With the'aforesaid and other objects in view, the character of the invention may be best understood by reference to the following description of one good form thereof Specification of Letters Patent.

Serial No. 199,178.

shown in the wherein:

Figure 1 is a perspective view of the snow remover shown herein as embodying the invention; and

Fig. 2 is a vertical section through the snow remover.

Referring to the drawings, the snow remover shown therein comprises a vehicle, in the present instance of the invention, in the form of a sled having runners 1 with uprights 3 at the forward ends thereof supporting a draft bar 5 connected to a tongue 7. The rear ends of the runners are connected by the drivers platform 9 reinforced by metal straps 11.

A frame may be mounted on the sled comprising side bars 13 having their rear ends connected by a cross bar 15 provided with trunnions l7 journaled inbearings formed by shoulders on the runners and ends 19 of the straps 11 bending forwardly and downwardly over said trunnions. The forward ends of the side bars 13 may be connected by a cross member conveniently in the form of an angle bar 21.

A. box may be mounted on the frame described and comprise a back wall 23 and side walls 25, the latter resting on and secured to the side bars 13 of the frame.

The box is provided with a bottom 27 fitted between the sides of the box. This bottom is adapted to slide to positions for supporting and discharging the contents of the box. To accomplish this, the rocking frame, referred to, may be provided with tracks 29 intermediate the side bars 13 and secured to the cross bars 15 and 21. The rear end of the bottom may be connected by a link 31 with a hand lever 33 pivoted on a bracket 35 secured to the drivers platform 9, referred to. The construction is such, that when the hand lever is rocked forward, the bottom will slide forwardly on its tracks until limited by its engagement with the cross bar 21, where it is in readiness to support the contents of the box. Then the hand lever is rocked rearward, the bottom will slide rearward along its supporting tracks and out from beneath the box, thereby discharging the contents of the box down between the runners of the sled.

At the forward end of the box is the scraper37 which may be covered by a metal protecting shoe 39 tapered to present a foraccompanying drawings,

ward thin edge and widening rearward to receive trunnions 41 journaled in bearings in the frame side members 13 adjacent the ends of the angle cross bar 21.

To manipulate the scraper, itmay be provided with an eye 43 secured thereto intermediate the ends thereof and connected by a link 45 with a hook 47 on the end of a hand lever 49 fulcrumed on a pin 51 on a bracket 53 mounted on a horizontal channel bar 55 having its ends secured to supports 57 mounted on the runners and strengthened by braces 59 and 61. The horizontal bar may be strengthened by a strut 63 and a truss rod 65 secured to the uprights 57. Preferably the bracket 53 is obliquely mounted on the bar 55, so that the hand lever will project obliquely rearwardly toward one end of the platform, where it will be conveniently accessible to the driver.

By the construction described the driver may conveniently grasp the hand lever and manipulate the scraper to active and inactive positions and to escape obstacles as desired.

Next willbe described means whereby the hand lever e9 may also serve to elevate the box into its position appropriate for supporting the contents of the box while being conveyed to the place where it is to be dumped. To accomplish this, suitable connections may be provided between the scraper and the box. In the present instance of the invention, these connections comprise stops 67 secured to the sides 25 of the box a substantial distance above the scraper when in its active position as shown in Fig. 1 When it is desired to elevate the box, it is merely necessary to depress the hand lever 49 beyond its range of movement for manipulation of the scraper, thereby rocking the scraper on its fulcrum upward into engagement with the stops 67. Further movement of the hand lever will lift the scraper, box and its frame upwardly, rocking the frame .on its trunnions 17.

Suitable means may be provided for securing the hand lever in its different positions'. In the present instance of the invention this isacc'omplished by a lock bar 69 pivotally connected to a bracket 71 on the back wall of the box. The hand lever has a bail 73 adapted to enter a notch 7 5 in said bar to hold the box in its lifted position. Said bail may enter a notch 77 on said bar to support the scraper in its lowered active position.

To support the box independently of the hand lever when it is in its lowered posi tion, stops in the form of blocks 7 9 may be mounted on the outer faces of the sides of the box and rest upon the upper edges of the runners. When the box is tilted upward. as described, these blocks will move up away from the runners, but when the box is lowered, they will engage said runners and appropriately limit downward movement of the box.

In operation the hand lever 33 is rocked forward to present the bottom 27 in posi-- tion to support the contents of the box. Then the hand lever 49 is rocked to its position shown in Fig. 1, thereby permitting the box to be supported by the engagement of the blocks 7 9 with the upper edges of the runners, and bringing the'scraper in position for engagement with the ground to guide snow therefrom into the box. If it is desired to cause the scraper to escape a stone or other obstacle in its path, or to interrupt scraping thereof for any purpose, the hand lever e9 may be depressed somewhat, thereby lifting the scraper to its position shown in full lines in Fig. 2. When the box has become filled with snow, the hand lever 4C9 may be depressed further, causing the scraper to engage the stops 69 and rock the aox and its supporting frame upward on the trunnions 17 to their positions shown in dotted lines in Fig. 2. The hand lever bail may then be inserted in the notch 7 5 of the it contributes to the support of the contents of the box.

After the snow has been conveyed to the place for its discharge, the hand lever 33 is rocked backward, thereby withdrawing the bottom from beneath the snow in the box, and permitting the same to discharge between the runners of the sled.

WVhile the invention has been described more particularly in connection with its use for removing snow, it will be understood that it is adapted for removing other material as desired.

It will be understood that the invention is not limited to the specific embodiment shown herein, but that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.

What is claimed is 1. In combination,

a vehicle, a box ,mounted thereon, a bottom for said box movable to positions for supporting and discharging the contents thereof, a scraper pivotally connected to the forward end of said box, stop means on said box,'a support on When the box is lifted, the

movable to positions for supporting and discharging the contents of said box, a scraper pivotally connected to the forward end of said box, stops on the sides of said box above said scraper, uprights on said vehicle, a bar connecting said uprights, a hand lever mounted on said bar, and a link connecting said hand lever to said scraper for lifting said scraper to said stops by a preliminary movement and lifting said box by a further movement.

3. In combination, a vehicle, a frame fulcrumed thereon having a cross bar adjacent the forward end of said frame, a box mounted on said frame, a bottom for said box slidable on said frame toward and from said cross bar to support and discharge the contents of the box, a scraper pivotally connected to said box in front of said cross bar and independently of said slidable bottom, means for raising and lowering said scraper relatively to said box, and means cooperating with said box and scraper for causing the box to move up with said scraper after the latter has been raised independently of said bottom a predetermined extent.

4. In combination, a vehicle, a box pivotally mounted thereon and having an open end, a scraper pivotally connected to the open end of the box, a support on the vehicle, an operating member mounted on said support, a connecting member having one end connected to said operating member and its opposite end connected to said scraper, that the latter may be tilted relatively to the box and the box may be tilted on the vehicle on movement of the operating member, means independent of said operating member to limit downward movement of the box on the vehicle, and means to hold said operating member in different positions of adjustment.

In testimony whereof I have signed my name to this specification.
